This is for a kit with the check valve. If you have a solenoid, just tap into the blue wire and ground the other wire coming from the solenoid. I got a request for this diagram, so here you go. :dance2:
Just so users know, the "not used" line coming out of the controller is a 5volt line to power other map sensors(gm 3bar or 2bar). The output from these can be connected to the green line and the ground is ,well, connected to ground.
